Abstract

This invention is directed to filtration systems comprising a venturi (261), flow control valves (221,241), filter and pump (121). In one specific embodiment the flow control valve (241) and venturi (261) are combined hereinafter known as a CHUF (55). The CHUF (55) may also contain concentrate release (82), and temperature (109), flow (107) and two pressure sensors (106,108) into a single structure. A continuous filtration system for liquid or gas applications is constructed by plumbing a CHUF (55) to a pump (121) and filter (141). The CHUF (55) is constructed of plastic, stainless steel or other materials. Different plumbing to the CHUF (55) positions the filter (141) in either series, parallel, or series and parallel with a venturi (261) and flow control valve (241) resulting in different pressures and flows at the filter (141). A single flow control valve (241) simultaneously controls inflow and outflow of the filtration system. Additional flow control valves (21,25,27) are used in a process to control pressure independent of flow at the filter (141).
